EN — Wide Flange (I-beam)
Wide flange beams (W shapes / I-beams) are the most common structural steel profile used in building construction. They are used for beams, columns, and girders in steel-framed buildings and bridges. Designed per AISC 360, Eurocode 3, and NBR 8800.
The UB 914x419x388 steel profile weighs 388.0 kg/m (260.74 lb/ft), has a depth of 921 mm (36.26 in), flange width 420.5 mm (16.56 in). Cross-sectional area: 48,923.5 mm². Moment of inertia Ix = 710,900.82 cm⁴, Iy = 45,424.52 cm⁴.
